I recently replaced 60 GB HD on an iBook G4 14", PPC 1.33. I bought a 320 GB Western Digital HD. Before installing the HD, I formatted it with Disk Utility. For some reason, disk utility could only recognize 300 GB. I'm not sure why. Could it be the external hard drive bay that I used? I've installed the HD, and I'm wondering if I can get the extra 20 GB out of my new HD.
